The Airless 0552946B Master Pack Tip Seal Kit contains all the service components needed to rebuild the tip seal area on the spray gun of an Airless LX‑30 airless paint sprayer. The kit typically includes the main tip seal, back‑up rings, O‑rings, and a retainer, ensuring a complete repair of the sealing stack that controls fluid flow at the spray tip.
A worn or damaged tip seal can cause fluid leakage from the gun when not triggered, a poor spray pattern, or difficulty achieving proper fan width. Over time, seals harden, swell, or become contaminated by abrasives and solvents. Replacing the entire tip seal assembly with this master pack restores positive shut‑off, consistent pattern quality, and reduces material waste.
| Positive shut‑off | Prevents dripping and leakage when the gun trigger is released |
|---|---|
| Spray pattern quality | Maintains proper fan shape and even material distribution |
| Consistent flow control | Ensures smooth, predictable fluid delivery at the tip |
| Gun drips when not triggered | Indicates worn or hardened tip seal |
|---|---|
| Uneven or distorted pattern | Seal failure can cause pressure fluctuations and pattern defects |
| Difficulty cleaning / clogging | Debris trapped in worn seals can affect tip performance |
| Visible damage | Cracks, swelling, or deformation of the seal material |
Airless part 0552946B is designed specifically for the spray gun of the Airless LX‑30 airless paint sprayer. It replaces the complete tip seal assembly; always verify fitment with your sprayer’s parts diagram.

When rebuilding the spray gun tip area, these associated components should be inspected and often replaced to ensure complete and reliable performance.
A worn tip seat can damage new seals; inspect the tip for scoring or pitting and replace if necessary.
Clogged or damaged filter can restrict flow and cause seal wear; clean or replace at the same time.
If the gun also shows signs of leaking at the trigger, consider rebuilding the entire gun valve stack.
